The J-integral has been implemented as a post processor into the commercial FE code ABAQUS. An automatic geometry reconstruction and intelligent remeshing procedure is applied. The crack tip is shifted by constant increments da. The J-integral is used to determine crack tip loading quantities such as stress intensity factors or the energy release rate. Crack paths are predicted applying a modified maximum energy release rate approach accounting for the fracture toughness orthotropy in rolled plates of aluminum alloy Al-7075-T651 where the anisotropy of elastic constants is negligible. A specimen with crack and hole is investigated. Young's modulus is E = 72000 MPa and Poisson's ratio is nu = 0.3. The vertical distance between crack and the holes center is e0 = 18 mm.
